| Abstract(in English) | A new fabrication technology for the conventional λ/4 IDT with λ/8 shift of a thin dielectric layer is proposed using the oblique angled photo-lithograpy process. These processes do not need a pricise alignment. Experimental result using a conventional λ/4 type unidirectional filters on 128゜Y-X LiNbO_3 substrate show 2.2dB and 2.6dB insertion loss and -20ppm/℃ temperature coefficient at 1GHz range. |
